RODERICK F. DANFORTH, OF BALTIMORE, MARYLAND.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 237,965, dated February22,. 1881.

Application filed June 10, 1880.

To all whom it may concern Beitknown that I, RODERICKF. DANFORTH, acitizen of the United States, residing at Baltimore, in the county ofBaltimore and State of Maryland, have invented certain new and usefulImprovements in Vapor-Burners; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawin gs, and toletters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to an improvement in vapor-burners for illuminatingpurposes.

A burner embodying my improvements will first be described, and. thoseparts or combinations which constitute the invention will then bedesignated in the claims.

In the drawings hereto annexed, Figure 1 is a vertical section of theburner. Fig. 2 is a plan view of the lower part of the burner.

The letter A designates the supply tube, packed with suitable materialb. This tube enters the rear of the upper part, 0, of the burner, fromwhich a small oil-passage, cl, leads to the front. Upon the front sideof the top part, 0, a disk or hood, 0, is secured by a shank, e. Aheating-cap, F, screws onto the said front side so as to inclose thedisk or hood and form in front of and about the hood avaporizingchamber, f. A vapor passage, g, is bored through the disk orhood and its shank, and through the front end of the top part, connecting with the vertical passage h, which is bored from the lower end, G, theentry of the bore being stopped by the screw-plug '5. Upon the frontside of the lower end is attached the burner-tip holder and thereceptacle for the entry of the oil to get up the heat.

The letter L denotes an oval-shaped shallow saucer or receptacle, whichrests on the upper side of the neck K, in front of the valve, having inits bottom an opening, at, through which the oil may rise and fill thesaucer when it is desired, at starting, to heat the chamber f, whichlatter is directly above the saucer.

The socket or holder P for the burner-tip (No model.)

19 is adapted to receive the tapered end of the tip, which is simply setinto the socket without fastening of any kind to retain it. The tip isslotted in the usual manner of gas-burners, the design being that theposition of the tip in the socket shall be such that the slot willextend in a direction crosswise of the heatercap. A vapor-passage, q,leads from the valve to the socket or burner-tip.

The needle-valve r closes communication from the passage h to q, andthis needle has ashank, on which is an enlargement or shoulder, 0", backof the passage h.

A stuffing-box, S, is screwed onto the rear side of the lower end, 0,and the extremity of the screw-threaded valve-shank is provided with asuitable knurled button or knob, R, which is attached to the shank afterthe box is supplied with its asbestus packing t, the screw part of theshank, it will be understood, being first passed through the packing andend of the box S. When the knob Ris turned in a direction to withdrawthe needle from its seat the shoulder r on the shank will press againstthe packing and restore it 'to a compact position and make it fit abouttheshank tight.

The oil which flows through the passage d discharges against the disk,which is but a short distance from the orifice of the passage, andthence passes around and below the shank, which secures the disk, andthen into the vaporizing-chamber in front of the'disk. The outlet orpassage g for the vapor, it will be noticed,is isolated from thesurrounding sides of the chamber. This arrangement of the disk is foundto serve admirably to secure the thorough vaporization of the oil in thechamber.

' l preferto make the vertical shank H, through which the passage h isbored, with four sidesthat is, square in cross-section-as seen in Fig.2, as when the greater amount of metal required by such constructionbecomes hot the liability of the vapor to condense is obviated.

Having described my invention, I claim and desire to secure by LettersPatent of the United States- 1.
